FIELD OF THE INVENTION

The present invention relates to installing software, and in particular,installing software hosted by application service providers.

BACKGROUND OF THE INVENTION

Many enterprises expect to use the Internet to reach far-flung agentsand customers. The Internet is a public network of computer networkseach with multiple nodes. The Internet uses open, standard protocols foraddressing nodes and passing information from one node to another. Auser accesses the Internet by logging onto one of the computers on thenetwork, often owned and operated by an Internet Service Provider (ISP).Typically, a user establishes a severable link between the user's owncomputer and the ISP computer. A client application program (a client)running on the user's computer interacts with a server applicationprogram (a server) running on one of the nodes on the Internet.

The World Wide Web (the Web) is a collection of resources available overthe Internet that are provided by various servers and that can beaccessed by a particular client called a Web browser using a hyper-texttransfer protocol (HTTP). Using a Web browser, a user can select aresource on the Web, identified by its Universal Resource Locator (URL)name, and have that resource presented to the user. The resource usuallyincludes textual information and often includes graphical, video andaudio elements.

For electronic commerce using the Web, the resource provided by theserver must include a mechanism for accepting user information. Forexample, many Web resources include forms for accepting product orders.Effective transactions may also require the resource provide access to adatabase. For example, a database enables the server to track inventoryof products available for purchase, or to find the account informationrequested by the client.

Any team that develops a Web site faces the challenge of having to dealwith developing multiple components. The term component is used hereinto refer to software (code or data) configured for a particular set ofend users. A component may be a database base object or a softwaremodule that performs functions such as generating screen displays,receiving user input, and carrying out data processing operations thatintegrate and select data, and present the data to a user or to otherprocesses which, in turn, present the data to the user. A set ofintegrated components that provide a particular functionality isreferred to as an application. For example, a set of components thatimplement an accounting system is referred to as an accountingapplication.

Applications reside and run on an application infrastructure. The termapplication infrastructure refers to computer resources that may beshared by multiple users, including hardware, operating system, diskstorage, and a database server, a web server, and an application server.

A particular configuration of an application infrastructure provided toan application is called an environment. For example, an environment maybe a particular configuration that includes access to a particulardirectory or set of UNIX operating system functions, to a quantity ofdisk storage, to a database server under a user account, to a fixednumber of database sessions, and to a tablespace (e.g. a set of datafiles used to hold data) dedicated to the application by a databaseserver.

Developing and maintaining an application for an enterprise is anenormously complex undertaking requiring expert personnel. While a largeenterprise has the finances to assemble a team having the requisiteexpertise, most enterprises are too small to assemble and support such ateam. Small to medium sized enterprises need a way to generate aneffective presence on the Internet, complete with an application,without incurring the full cost of a team of programmers and experts.

To offset these costs, enterprises employ service companies to maintainthe applications and environments in which the applications run. Thetechnique of using service companies to maintain and operateapplications is referred to as application hosting. A hostingenvironment may be accessed via, for example, the Internet, or anextended intranet. Application hosting can reduce the cost of managingapplications because it allows companies to share the resources neededto run an application, resources that not only include an applicationand its environment, but the experts needed to maintain the applicationand its environments, including computer administrative supportpersonnel.

The term “user” is used herein to refer to a particular entity for whoman application and its associated data is being hosted. The entity maybe a human individual or an enterprise.

Application hosting reduces costs by enabling an enterprise to combineresources with other enterprises to manage the complex process ofmaintaining applications and their environments. Another way to reducecosts is to reduce the complexity of this process. Various complex tasksincluded in this process are the creation and configuring of anenvironment needed to develop and run an application, and theinstallation of various application components into these environments.These tasks are collectively referred to as deploying software.

Producing software requires maintaining multiple environments to runvarious copies and versions of an application. These multipleenvironments include a development environment, a testing environment, astaging environment, and a production environment. The developmentenvironment is used to develop software. Access to the environment islimited to developers. The testing environment is used to test software.Access to the environment is limited to testers. The productionenvironment is an environment where an application is used by an enduser. The staging environment simulates a particular productionenvironment, and is thus configured similarly to a particular productionenvironment, and is used to test how well an application will run in theproduction environment.

Deploying an application is a laborious and complex process. Those thatperform the task have to deal with a large range of technology. Theprocess entails, for example, analyzing an application to determine asuitable environment for it, identifying the application's variouscomponents, installing and configuring hardware and operating systemsfor a new environment, configuring an existing environment, runninginstallation routines to install application components, and configuringnetwork and security mechanisms.

Based on the foregoing, it is clearly desirable to provide a system thatreduces the complex task of deploying software.

SUMMARY OF THE INVENTION

Techniques are provided for deploying applications hosted by anapplication service provider. According to an aspect of the presentinvention, an application in a first environment is automaticallydeployed to a second environment in response to receiving a request overa network from the party for whom the second environment is beinghosted. The first environment may be an environment where applicationsare developed by the party over the network. Deployment of theapplication may entail provisioning of an environment for theapplication.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A method and apparatus for deploying an application are described. Inthe following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of the present invention. It will be apparent, however, toone skilled in the art that the present invention may be practicedwithout these specific details. In other instances, well-knownstructures and devices are shown in block diagram form in order to avoidunnecessarily obscuring the present invention.

Described herein is a process for deploying an application into a hostedenvironment. The process of collecting information about the deploymentmay be initiated through user interfaces transmitted to a user over theInternet. After the requisite information has been collected, the actualdeployment operation is initiated by clicking a command button in theuser interface. The deployment is then completed without humanintervention. Because deployment may be completed in this manner, thedeployment process is referred to as “one-click deployment”.

One-click deployment automates the onerous task of deploying software,thereby reducing the cost of maintaining and developing applications. Aone-click deployment process is illustrated herein by using the processto deploy an application from the hosted development environment wherethe application is developed, to other environments, such as thetesting, staging, and production environments. The development of anapplication is an iterative process involving repeated deploymentsbetween environments. For example, when developing an application, itmay be developed, deployed to a testing environment, tested, and thenfurther developed and redeployed to a testing environment. Automatingthe deployment process significantly reduces the time and cost incurredto develop an application.

The capability to cheaply and quickly deploy an application from ahosted development environment to another hosted environment createssignificant advantages for vendors of packaged applications, especiallyrelatively small vendors. A vendor may develop an application on ahosted environment, where it can be readily deployed to customers. Thevendor can realize the benefits of such a deployment system while beinginsulated from the burdens of managing or undertaking deployment of theapplication.

Development Service Provider System

FIG. 1 shows development service provider system 180 and some of itsconstituent parts, according to an embodiment of the present invention.A development service provider system hosts environments andapplications for users, and provides tools that may used by the users torequest environments and develop the applications. Development serviceprovider system 180 includes appliances 120, development environment130, and configuration manager 190. Appliances 120 and developmentenvironment 130 are coupled to development service provider system 180via a network (not shown), such as a local area network or a virtualprivate network.

Appliances 120 include appliances 120-1 through 120-N. Appliances 120are devices that are (1) configured to participate with configurationmanager 190 to integrate themselves into development service providersystem 180, and (2) to participate with configuration manager 190 toprovision environments. An example of an appliance is a databaseappliance described in Ellison.

The term provisioning refers to operations carried out to enable a setof resources to be used in a particular way by an entity. For example,provisioning a database server entails operations that allow a user toaccess the database server, operations such as establishing an account,or, if needed, installing the database server. Provisioning a digitalsubscriber line for a home may entail establishing an account on aremote server connected to the home's phone wiring, and if needed,adding a network card to the home computer and as well as otherhardware.

Provisioning the resources for an environment is referred to asprovisioning the environment. Thus, provisioning an environment mayentail configuring resources such as a web server and database server,and consumable resources, such as storage space, central processing unit(CPU) usage, and connection bandwidth.

Depending on the resources hosted for a user on an appliance, anappliance may be either a dedicated device or a shared appliance sharedby a plurality of users. If the customer has exclusive access to allresources provided by an appliance, that appliance is configured as anappliance dedicated to that user. If, however, a customer requires onlya portion of the resources that are provided on an appliance, then thatappliance can be shared among several customers. The user may shareaccess to many of the resources that reside on an appliance. Forexample, users may share a database server and web server.

An appliance may have multiple environments for multiple users. Anappliance 120 has testing environment 122, staging environment 124, andproduction environment 126 for a particular user. An appliance may beconfigured for any combination of environments for any combination ofusers. For example, an appliance may have the testing environments ofmultiple users, or have the staging and production environment of asingle user.

Development environment 130 is an environment shared by multiple users.It hosts applications 138, which are applications being developed byusers. Applications 138 include application 138-1 through 138-M, each ofwhich is developed by a particular user.

Applications 138 are developed by users using development tool 136 indevelopment environment 130. An application development tool, such asdevelopment tool 136, is software that interacts with a user to generatecomponents of an application according to user input provided by theuser.

Development tool 136 generates a range of components. This rangeincludes web pages, user forms, and database objects (e.g. tables,views), and code that implements the processes and functions performedby an application.

A user interacts with a development tool 136 through wizards. A wizardis a series of one or more screens (e.g. user forms) for receiving inputfor performing an operation. The screens may be transmitted as one ormore web pages to a user over the Internet. These web pages may containembedded code, scripts, or programs that are executed at a client. Theseprograms can be, for example, Java applets, Java scripts, or ActiveXcontrols. The programs may be stored temporarily in the cache of aclient, or more permanently as, for example, one or more plug-inapplications.

Configuration manager 190 is a combination of software and hardwareresponsible for configuring appliances 120 and other entities indevelopment service provider system 180. Configuration manager 190includes provisioning tool 162, environment template tool 164, andrepository 170. Repository 170 contains metadata describing resourcesavailable on appliances 120 and how they are configured for users.

FIG. 2 is a block diagram that shows repository 170 in greater detail.Referring to FIG. 2, repository 170 includes user resources 210,environment templates 230, and environment specifications 230. Userresources 210 include data describing the resources and environmentshosted for a particular user.

Environment templates 220 are a collection of environment templates. Anenvironment template describes a logical grouping of resources.

Environment specifications 230 are a collection of environmentspecifications. An environment specification contains detailedparameters about a particular environment on an appliance, includingwhat applications use the environment and how the resources areconfigured for the environment. An environment specification mayspecify, for example, that a particular environment includes a databaseserver and a web server, and how these resources are configured for aparticular application, including sizing parameters. Sizing parametersspecify how much of a resource is available to a user or application.Sizing parameters for a database server may specify, for example, thenumber of rows or megabytes of disk storage used for a particularapplication.

Environment template tool 164 is used to define user-defined environmenttemplates. Environment configuration tool 164 provides wizards withwhich users may interact to define environment templates. Otherenvironment templates may be default environment templates, whichdescribe commonly used groupings of resources. Default environmenttemplates are defined by the administrators of development serviceprovider system 180.

A provisioning tool, such as provisioning tool 162, is a combination ofhardware and software that interacts with an “application source”, suchas development environment 130, to install the components of anapplication and, if needed, provision a “target environment” for theapplication. An application source is a combination of software andhardware configured to supply the code and data needed to install thecomponents of an application. An application source may simply be arepository of code or data, an installable package (e.g. Java ArchiveRepository), or a server configured to interact through an applicationprogrammer interface (“API”) to supply application components. If thetarget environment already contains a version of the application toinstall, the provisioning tool may update the version of the applicationin the target environment. In addition, a provisioning tool may accessother sources of information to determine how to install an applicationand provision an environment. For example, provisioning tool 162accesses an environment template to determine what resources toprovision for an application and how and accesses repository 170 todetermine where to install the application components. An example of aprovisioning tool is the IDSP provisioning process and databaseprovisioning process described in Baffier.

One Click Deployment to New Environments

FIG. 3 is a flowchart depicting a process for deploying an applicationto a new target environment. The following process involves userinteraction with development service provider system 180. Thisinteraction occurs through one or more wizards transmitted to a clienton behalf of a user. In the following description of the process, thewizards are described as receiving user input or performing otheractions. However, this is just a convenient way of expressing that adevice is performing these actions in response to executing a wizard.

Referring to FIG. 3, at step 316, a request is received to deploy anapplication. There are a variety of ways a user may request thedeployment of an application. The user may have the ability to request aparticular application as part of a larger set of functions that may beaccessed through a wizard provided by development tool 136. Alternately,an administrator may issue a request by accessing a function that ispart of a larger set of functions used by administrators to managedevelopment service provider system 180.

At step 322, the user selects an environment template from a list ofenvironment templates listed by the wizard. Alternatively, anenvironment template may be automatically selected based on informationabout the application stored in development tool 136. At step 324, theuser selects other resources to provision in the environment. The otherresources are resources not covered by the selected environmenttemplate. The user may select from a list of resources presented by thewizard.

At step 328, the user provides sizing input to the wizard. The sizinginput may be any information used to determine sizing parameters. Suchinput may be, for example, the number of users concurrently accessingthe application, how often the user accesses the application, the numberof transactions that may occur within a period of time, and a number ofrecords to generate. The present invention is not limited to anyparticular type of sizing input.

At step 336, the user provides input to initiate the actual deploymentof the application. The input may be provided by clicking a commandbutton presented in the wizard. In response, the applicationprovisioning tool 162 provisions a target environment and installs theapplication. More specifically, at step 348, provisioning tool 162provisions the environment. This step may entail a variety of tasks suchas (1) determining sizing parameters based on the sizing input provided,(2) selection of an appliance that has sufficient available resources,and (3) provisioning resources specified in steps 322 and 324.

For example, assume that a testing environment is being provisioned.Based on input provided at step 324, the environment should includeaccess to a database server that supports up to ten user sessions andthat has 120 megabytes of storage. The provisioning tool selects anappliance that has a database server and at least 120 megabytes ofstorage that may be used by the database server. Provisioning tool 162then configures a user account through which the application to installmay access the database server. The user account supports up to ten usersessions.

At step 354, provisioning tool 162 installs the application. Installingthe application may entail such tasks as (1) retrieving code modules forthe application from the development environment and installing them inthe target environment; (2) creating a tablespace to hold data for thedatabase objects defined for the application; and (3) creating in thedatabase server a tablespace that meets the sizing requirements, as wellas database objects.

At step 360, provisioning tool 162 updates repository 170. Specifically,environment specification 230 is updated to record the existence of thenew target environment, the sizing parameters, and which application hasbeen installed within the target environment. User resources 210 areupdated to record the provisioning of the new target environment for theuser, and the fact that the application is installed within the targetenvironment.

One Click Deployment to an Existing Environment

Developing software is an iterative process which may involve deployingand re-deploying applications to environments that have been establishedbefore a deployment is initiated. For example, when developing anapplication, it may be developed, deployed to a testing environment,tested, and then further developed and redeployed to a testingenvironment. Thus, an application may be deployed, numerous times, to anenvironment that already exists. Each new deployment may involve theinstallation of new application components or new versions ofapplication components.

FIG. 4 is a flowchart depicting a process performed to deploy anapplication to an environment that has already been established. Thefollowing process involves user interaction with development serviceprovider system 180. This interaction occurs through one or more wizardstransmitted to a client on behalf of a user.

Referring to FIG. 4, at step 416, a request is received to deploy anapplication. As discussed with respect to step 316, there are a varietyof ways a user may request the deployment of an application.

At step 422, the user selects a target environment to deploy to. Theuser may select from a list of environments presented by a wizard. Thelist contains environments created for the user. Information from whichthe list is derived may be obtained from user resources 210.

At step 428, provisioning tool 162 retrieves configuration informationfor the selected target environment from repository 170, and inparticular, environment specifications 230. The information is neededbecause the environment may need to be configured so that newapplication components, or new versions of application components, mayaccess the resources of the target environment.

At step 436, provisioning tool 162 re-installs the application.Re-installing an application may involve replacement of components withnewer versions of those components, installation of new components, andreconfiguration of the environment so that the updated application mayaccess the resources as needed. Installation of new components mayinvolve, for example, installing new code modules and defining orre-defining new database objects.

In the case of deployment from a staging environment to a productionenvironment or a testing environment to a staging environment, steps 416and 422 may be performed through one or more wizards provided byconfiguration management tool 180. In addition, access to these wizardsmay be limited to personnel responsible for managing deployment andconfiguration.

Other Embodiments

The present invention has been illustrated using specific embodimentsthereof. However, other embodiments are possible.

For example, use of the Internet is not required. Users may interactwith the system of an application service provider over any type ofpublic or private network.

An application may be deployed from an application source other than adevelopment tool. For example, a one-click deployment process may beused to install a packaged application. Such a process would entailselection of the application package and installation of the packageinto a new or existing environment, provisioned as needed.

Use of appliances is also not required. The methods described herein maybe implemented using various other types of computers and devices, suchas general purpose computers.

Hardware Overview

FIG. 5 is a block diagram that illustrates a computer system 500 uponwhich an embodiment of the invention may be implemented. Computer system500 includes a bus 502 or other communication mechanism forcommunicating information, and a processor 504 coupled with bus 502 forprocessing information. Computer system 500 also includes a main memory506, such as a random access memory (RAM) or other dynamic storagedevice, coupled to bus 502 for storing information and instructions tobe executed by processor 504. Main memory 506 also may be used forstoring temporary variables or other intermediate information duringexecution of instructions to be executed by processor 504. Computersystem 500 further includes a read only memory (ROM) 508 or other staticstorage device coupled to bus 502 for storing static information andinstructions for processor 504. A storage device 510, such as a magneticdisk or optical disk, is provided and coupled to bus 502 for storinginformation and instructions.

Computer system 500 may be coupled via bus 502 to a display 512, such asa cathode ray tube (CRT), for displaying information to a computer user.An input device 514, including alphanumeric and other keys, is coupledto bus 502 for communicating information and command selections toprocessor 504. Another type of user input device is cursor control 516,such as a mouse, a trackball, or cursor direction keys for communicatingdirection information and command selections to processor 504 and forcontrolling cursor movement on display 512. This input device typicallyhas two degrees of freedom in two axes, a first axis (e.g., x) and asecond axis (e.g., y), that allows the device to specify positions in aplane.

The invention is related to the use of computer system 500 forimplementing the techniques described herein. According to oneembodiment of the invention, those techniques are performed by computersystem 500 in response to processor 504 executing one or more sequencesof one or more instructions contained in main memory 506. Suchinstructions may be read into main memory 506 from anothercomputer-readable medium, such as storage device 510. Execution of thesequences of instructions contained in main memory 506 causes processor504 to perform the process steps described herein. In alternativeembodiments, hard-wired circuitry may be used in place of or incombination with software instructions to implement the invention. Thus,embodiments of the invention are not limited to any specific combinationof hardware circuitry and software.

The term “computer-readable medium” as used herein refers to any mediumthat participates in providing instructions to processor 504 forexecution. Such a medium may take many forms, including but not limitedto, non-volatile media, volatile media, and transmission media.Non-volatile media includes, for example, optical or magnetic disks,such as storage device 510. Volatile media includes dynamic memory, suchas main memory 506. Transmission media includes coaxial cables, copperwire and fiber optics, including the wires that comprise bus 502.Transmission media can also take the form of acoustic or light waves,such as those generated during radio-wave and infra-red datacommunications.

Common forms of computer-readable media include, for example, a floppydisk, a flexible disk, hard disk, magnetic tape, or any other magneticmedium, a CD-ROM, any other optical medium, punchcards, papertape, anyother physical medium with patterns of holes, a RAM, a PROM, and EPROM,a FLASH-EPROM, any other memory chip or cartridge, a carrier wave asdescribed hereinafter, or any other medium from which a computer canread.

Various forms of computer readable media may be involved in carrying oneor more sequences of one or more instructions to processor 504 forexecution. For example, the instructions may initially be carried on amagnetic disk of a remote computer. The remote computer can load theinstructions into its dynamic memory and send the instructions over atelephone line using a modem. A modem local to computer system 500 canreceive the data on the telephone line and use an infra-red transmitterto convert the data to an infra-red signal. An infra-red detector canreceive the data carried in the infra-red signal and appropriatecircuitry can place the data on bus 502. Bus 502 carries the data tomain memory 506, from which processor 504 retrieves and executes theinstructions. The instructions received by main memory 506 mayoptionally be stored on storage device 510 either before or afterexecution by processor 504.

Computer system 500 also includes a communication interface 518 coupledto bus 502. Communication interface 518 provides a two-way datacommunication coupling to a network link 520 that is connected to alocal network 522. For example, communication interface 518 may be anintegrated services digital network (ISDN) card or a modem to provide adata communication connection to a corresponding type of telephone line.As another example, communication interface 518 may be a local areanetwork (LAN) card to provide a data communication connection to acompatible LAN. Wireless links may also be implemented. In any suchimplementation, communication interface 518 sends and receiveselectrical, electromagnetic or optical signals that carry digital datastreams representing various types of information.

Network link 520 typically provides data communication through one ormore networks to other data devices. For example, network link 520 mayprovide a connection through local network 522 to a host computer 524 orto data equipment operated by an Internet Service Provider (ISP) 526.ISP 526 in turn provides data communication services through the worldwide packet data communication network now commonly referred to as the“Internet” 528. Local network 522 and Internet 528 both use electrical,electromagnetic or optical signals that carry digital data streams. Thesignals through the various networks and the signals on network link 520and through communication interface 518, which carry the digital data toand from computer system 500, are exemplary forms of carrier wavestransporting the information.

Computer system 500 can send messages and receive data, includingprogram code, through the network(s), network link 520 and communicationinterface 518. In the Internet example, a server 530 might transmit arequested code for an application program through Internet 528, ISP 526,local network 522 and communication interface 518.

The received code may be executed by processor 504 as it is received,and/or stored in storage device 510, or other non-volatile storage forlater execution. In this manner, computer system 500 may obtainapplication code in the form of a carrier wave.

In the foregoing specification, the invention has been described withreference to specific embodiments thereof. It will, however, be evidentthat various modifications and changes may be made thereto withoutdeparting from the broader spirit and scope of the invention. Thespecification and drawings are, accordingly, to be regarded in anillustrative rather than a restrictive sense.
